SPECIFICATION forming part of Letters Patent No. 388,202, dated August21, 1888.

Application filed January 4, 18 8. Serial No. 259,809. No model.)

To all whom it may concern:

Be it known that I, ALMON K. hrs, of Missoula, in the county ofMissoula, Montana Territory, have invented anew and useful Improvementin Medical Instruments, of which the following is a specification.

In the topical treatment of diseases of the nasal, throat, and lungcavities great difficulty is experienced in applying powdered medicinalsubstances to the affected parts.

The object of my invention is to provide a simple and inexpensiveinstrument which is adapted to perform this function with convenience,certainty, and dispatch.

The invention embodies certain features of instruments employed fordestroying insects on animals, to wit: a compressible air-bulb, apowder-receptacle having a discharge-nozzle, and also a perforated platefor hindering the escape of large particles of the powder (or othersubstance) from said receptacle into the nozzle.

My improved instrument is composed of parts constructed and combined ashereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of theinstrument in use. Fig. 2 is a longitudinal section of thepowderreeeptacle. Fig. 3 is a plan view of the cover of the latterinverted.

The bulb A and tube B are formed of rubber similar to those employed inthe construe tion of atomizers in common use. The tube B connects withthe powder box or receptacleO at or near the bottom thereof, so that theair forced into it will enter at such a point as to enable it to take upa portion of the powder and carry it out through the openings in thecover a of the receptacle. In this instance the cover is shown securedby a frictioirjoint; but I propose to attach it by means of ascrewthreaded joint in some cases. The perforations in the cover are ofso small diameter as to allow only the finest or most impalpableportions of the powder to pass through them. A rigid handle, I), isattached to the under side of the box O for convenience in holding andmanipulating the instrument.

The practical use of the latter is as follows: A suitable quantity ofthe finclypowdered medicinal substance to be applied to the diseasedsurfaces is placed in the receptacle 0 and the cover a replaced. Thebulb A is then held in one hand while the other is applied to the handleI) of the powder-receptacle C, and when the perforated portion of thelatter has been properly placed or directed with reference to the partsto be treated the bulb is pressed more or less forcibly, thus drivingair into the receptacle O, wherein it takes up a portion of theimpalpable powder and carries it through the openings in the cover a inthe form ofjets, which convey it to and deposit it upon thediseascdsurfaces. The small diameter of the openings in the coverprevents escape of any coarse particles of the powders, so that aserious objection incident to the digital application of medicinalpowders to the nasal and other passages is avoided. The powder thusexpelled follows and is carried along in the air-current produced by theact of inhalation, and thus reaches the innermost cavities and surfaceswhich are not otherwise accessible to treatment. The top of thereceptacle C may have different forms to better adapt it for use in thenose or throat.

Vhat I claim is- The improved instrument for applying powdered medicinalsubstances to the nasal,throat, or lung cavities, the same consisting ofthe powder-reccptacle having small perforations in its top and asuitable handle, the compressible air bulb,and the flexible tubeconnecting it with said bulb, as shown and described, whereby thecompression of the latter forces air into contact with the powder in thereceptacle, whence it is expelled in jets that carry along some of thefine iinpalpable portion of the powder, as specified.
